* build-aux/bootstrap (slurp): Work even in environments where
"ls" defaults to "ls -A".  Put in a FIXME, though, since the
current code does not slurp files whose names start with ".", and
this looks like it might be a troublesome area.

If there's a GPL vN copyright comment, require that N == 3.

Run the coreutils-specific code only if tests/Makefile.am.in exists.
* build-aux/bootstrap (mam_template): Move definition out of loop.

Create symlinks for gl/{lib,m4}/*, just as for gnulib/{lib,m4}/*.

* build-aux/bootstrap (symlink_to_dir): Rename function from
symlink_to_gnulib.  Add a directory parameter.  Update all
callers.
(cp_mark_as_generated): Also check for -- and link to -- files in
gl/.

Adapt to deeper hierarchy in gnulib.
* build-aux/bootstrap (symlink_to_dir): If the destination
directory doesn't exist, create it. This is required at least for
"lib/uniwidth/cjk.h".

* build-aux/bootstrap: Now that generated Makefile.am files
are no longer under version control, they must be created at
bootstrap time.
